How to Decrypt and Extract WhatsApp Database

Nowadays , WhatsApp has become the best interoperable Instant Messaging and VoIP (Voice over Internet Protocol) and Multimedia platform for the end users that provides them an well-serviced environment for Instant Messaging , Voice/Video Calling , File Transfer such as Documents , Videos and Images easily at the scale with high-end encryption encapsulated into it globally .

WhatsApp basically uses a standardised protocol for Instant Messaging called Extensible Messaging and Presence Protocol (XMPP). It basically uses one of it's most valuable service called Jabber for user account at the time of Installation using the phone no. as the username i.e. (Jabber ID: [phone number]@s.whatsapp.net) and then it estimates all smart phones from it's address book with the help of it's centralised database for adding contacts automatically to their contact list and then it also allows Multimedia Messaging to the end users with the help of HTTP server and generates a hyperlink to the content with Base64 encoded.

Before Demonstration , I'd like to write about the working principle of WhatsApp high-end Encryption

As you know that the Multimedia Messaging and other type of data are simply the decrypted data and need to be encapsulated in order to securely communicate with each other through a communication channel.

So Firstly , the Plain Text is encrypted using Private Key for the Data Encapsulation

i.e. PlainText + Secret Key == Data Encapsulation (Encrypted Data)

Once the data has been received by the receiver needs to be decrypted i.e. plain text using the same Secret Key for it

The Main Problem with the Technique is the usage of Same Key for both encryption and decryption
So , if the sender sends the data to the receiver , the third party is likely to be able to eavesdrop and forge and sniff the conversation , data etc between sender and receiver which could create a massive problem to both of them

In order to overcome the problem , WhatsApp basically uses Two Keys for both encryption and decryption. These two keys are mathematically so related to each other that one key can encrypt the PlainText to Encrypted Data which can be later on decrypted by receiver

Both of your public and private keys are generated on your smartphone at the time of installation , So what does that mean by high-end encryption

As your private key is generated on your mobile , The third party Attacker cannot decrypt your messages due to the implementation of private key.

The 60 digit number shown above is shorter form of addition of your and your contact's public key. Remember, you use your contact's public key to encrypt outgoing message and your contact uses their private key to decrypt and vice versa.

Scanning QR code or comparing those 60 digit number is a way to verify and ensure that you are using correct public key of your contact and no one (whatsapp server or others) is spoofing you with wrong public key.

Now let me cut to the chase and write about the mechanism of both decryption and extraction of WhatsApp Database

You got to be thinking that it's impossible to just decrypt and extract the WhatsApp Database so easily with such high-end security attached to it

But let me tell you straight that it's possible and very easy to decrypt and extract the Database easily with the help of built-in tools available today in this technology

After all , Nothing is Impossible in today's technology

If there exists the technology then obviously there exists security tools too

There are following prerequisites software and tools need to be downloaded and installed before it

In order to enable USB Debugging , Please navigate to Settings --> Developer Options --> Enable USB debugging. Please tap multiple times on Build Number under About Phone unless and until you become the developer if you find no developer option under the Settings option

Note :

01. I apologise Linux and Mac OS X users for the following below demonstration

02. Windows end users must have minimum knowledge about Windows OS for it

03. This is to be advised that it's for the education purpose , any illegal activity against any other unauthorised devices could lead to jail
